This paper makes use of the leak in Word encrypfion mechanism to decrypt word document in constant time, which has nothing to do with the key length. At the same time, an approach based on MapReduce paradigm is presented to to achieve Word document decryption, which simplifies the design of distributed application. The experimental result proves the validity of the proposed approach and the low consumption among distributed computing nodes.
